If the final exit status is nonzero, I think that's not a problem for
the firstboot script.
The whole command seems to make sense also when nm-online, systemctl, or
both, are missing (a missing command results in exit status 127).
Unfortunately, this does not work. Even though the command succeeds very
quickly (implying network is available), the DNF throws a CURL error
that it cannot access the repo (DNS resolution failure). So basically
"nm-online" lies.

My current workaround is to use "/usr/bin/sleep 60" instead
of the
"/usr/bin/nm-online -s -q --timeout=30" command in the service unit
file.
:/
NB, when I log in at the root prompt of the just-firstbooted-guest (on
tty1), and run "nm-online -x -q", it succeeds alright, and I can even
ssh into the guest... (more precisely, I get an ssh password prompt; I
can't actually log in as root via ssh due to the default sshd config not
permitting that).
We can't rely on "nm-online" if it doesn't do its advertized job!
